Application tiled January 28, 19.14. Serial No. 814,907.

To all whom it may concern:

'Be it known that I, JAMEs G. Crozes, a citizen of the United States, residing at Ceda-rBapids, in the county of'l'ninnl and State of Iowa, have invented certain new and useful Improvements in Reversible Self- Cleaning Rakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as'w'ill yen-` .invention is to provide a rake of this nature having a rotatable tooth carrying bar secured to the rake head, said head being so constructed as to hold the teeth in proper operative position when being drawn toward the operator and to allow the teeth to swing upwardly toward the head when moved away from the operator, so as to free itself of all'accumulations.

Asa lfurther object, the invention contemplates the `provision of a self-cleaning rake of a. reversible nature, so that either end of the teeth may be employed, depending upon the character of the work to be performed.

With these and other objects in view as will become more apparent as the descrip tion proceeds, the invention' consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fullyl described and claimed.

For a complete understanding of mv invention, reference is v,to be had to the following description andsaccompanying drawings, 1n which- Figure 1 is a side elevation of my im:

proved rake-the teeth being shown in inoperative'position by dotted lines. Fig. 2 1s a top` plan view of the rake, with the teeth shown in two ositions Fi 3 'is a fragmentary section ta en on the p ane of line 3 3 of Fig. 2, Fig. 4 isa section taken Ion the plane of line 4--4 ofFig. 2, and Fi isfa f ramentary bottom plan-view of e rake numerals, 1 designates the' rake which is connected to the head, generally designated 2, mprising a socket'. 3 and curved oar 4 w ich forms in substance a fork. This bar' is reinforced .on its outer side .by a'central longitudinal rib 5 and has its terminals exten ed laterally,l as indicated by the numeral 6. A sto block 7 is st integrally with the bar 4: f etween the ends thereof and has its upper edge extended outwardly in advance of the lower edge to form a lip, indicated by the numeral 8. A tooth carrying bar 9, which is circular in cross section, is rotatably secured to the head 2 by a pair of straps l0. These straps are attached to the laterally extending portions 6 of the fork or bar 4 by bolts 11 and nuts 12. The bolts extend through registerlng openings formed in the termina s of the straps and in the rib 5, and the straps encircle the bar 9 to hold it in engagement with the concave outer faces 13 of the fork and the curved outer face 14 of the block 7. vThe teeth are formed by a plurality of .U-shaped members 15 which extend transversely through the bar 9. These teeth extend some distance on each side of the bar 9, but have a greater portion of their `length disposed on one side than on the other, as clearly shown in the drawings so that they will normally hang in a vertical plane. l

It will be noted that the lip 8 is engaged by the teeth which are disposed between the straps 10 and acts as a stop to limit the rotation of the bar 9 so as to hold1 the teeth in working position when the rake is 'being drawn toward the operator. When the rake is moved forwardly for another stroke, the resistance offered by the ground causes the teeth to swing rearwardly, as indicatedby the dotted lines in Fig. 1, and allows them to discharge all accumulations; As soon as the working stroke yis started, the teeth swing back mtooperative position as shown by solid linea in the drawings. when it is desired to reverse the rakeso aa to use the bight portions of the ULshaped members, the necessary rearrangement of parts may be guickly made by detaching the straps 10 rom the head, and turning the, bar 9 so that the pointed ends of the teeth are uppermost.- From the -fore oing description taken in connection with t e accom anying draw' `it will be apparent thatil digg Referring in detailzto thedrawn?,

, .in-whe simple construction, anni it will haveprovi reversible self-cleaning rake of strong and stood that while I have shown and described the preferred embodiment of my invention, minor changes in construction, combination and arrangement of parts may be made without departing :from the spirit and scope of the invention as claimed. l

Having thus described my invention, I claim y In a reversible self-cleaning rake, a socket having a fork, a cylindrical tooth carrying bar extending transversely across the terminals of said fork, straps encircling said bar and removably connected to the fork -to hold the bar thereagainst, a plurality of Copies of "this patent may he obtained for ive cent teeth extending transversely through the 15 bar projecting on opposite sides thereof, and a stop block arranged between the arms of said fork having an outwardly projectingv lip to receive the upper ends of certain of said teeth to limit the rotation of the bar 2O in one direction during a Working stroke.

In testimony whereof I aihx my signature in presence of two witnesses.
